Ivy, I am pretty sure the media named Jackie Nose as the new boss (not acting boss) in 2009 or 2010. I can't find the article since it is old news.
Always go with an indictment over some press article. Peter Gotti was still the recognized official boss at that point.
At various times relevant to this Indictment–, the defendant JOHN D’AMICO, also known as “Jackie the Nose” and “Jackie,” was a solidar, captain and acting boss in the Gambino family.http://graphics8.nytimes.com/packages/html/nyregion/20070207indict.pdf
